In other words, when you upgrade to the latest and greatest, if you don't sell your previous device, do you downgrade it to be just a music player (perhaps in a dock speaker in the living room or bedroom) or something else? For example, I know of a few friends that since they upgraded to the 6+, their 4S' now reside at their front door at home which controls all the house lights. Another friend has his 5S magnetically mounted to his fridge door where he too can control the house lights but more interestingly has only food cooking apps and YouTube. Another friend has his 4S mounted in his shower which controls bluetooth speakers in the bathroom. Crazy ideas... ..Just wondering if anyone has interesting ideas for old devices, considering selling these old phones don't yield too much, especially if they have some damage.
